More Information
Summary:Disclosed is a multimodal propylene impact copolymer composition with improved stiffness while maintaining good impact strength. The continuous phase has a broad PI and provides the multimodal propylene impact copolymer composition with excellent processability. Thermoformed articles made from the multimodal propylene impact copolymer exhibit improved rigidity and good impact strength. La présente invention concerne une composition de copolymère résistant aux chocs de propylène multimodal ayant une rigidité améliorée tout en maintenant une bonne résistance aux chocs. La phase continue a un PI large et produit la composition de copolymère résistant aux chocs de propylène multimodal ayant une excellente aptitude au façonnage. Des articles thermoformés fabriqués à partir du copolymère résistant aux chocs de propylène multimodal présentent une rigidité améliorée et une bonne résistance aux chocs.
